Application filed September 7, 1888. Serial No. 284,806. (No model.)

To aZZ whom it may concern:

Be it known thatl, HENRY M. Rosa, a cit izen of the llnited States,residing at Waterman, in the county of .l)e Kalb and State of Illinois,have invented certain new and useful Improvements in Disk Cultivators;and I do declare the .following to be a full, clear, and exactdescription of the invention, such as will enable others skilled. in thearlto which it appertains to make and use thepamo. 11

I11 the employment of disk and other cult ivators mueh difticulty hasbeen ex 'ic-srieneed in obtaining an et'tieieut disintegration andstirring; of the soil in imn'lediate proximity to the plants without atthe same time injuring the latter.

It is the object of my invention to olvtain this desired degree orcharacter of en. ti y" 'ion J and thereby to cause a growth and deel'opment of the plant much beyond that which is attained by theonlinary cultivator.

My invention also secures other advair tages in theconstruction andnu'sansot adjustment oit' certain parts ot. the eultivutor, ashereinafter ilarticularly poi nted on t.

The invention relates to the ;irrai1 .;'4'-||ne1|t of the disks of thegangrelal ive to each other, whereby thew-inner disk or disks will beset at an angle to the outer disk or disks, and. will advance in aposition more. nearly parallel with and at a less angle to the row ofplants being cultivated than will the outer disk or disks of the gang. tnder this arraiic'ement the cutting-Mgr ot' the inner disk of one gzrngcan be brought very close to -say within seven inches, orl'lIQl'tWtiltllliri ll( eut'tingcdge of the inner disk of the opposit ogang, thereby insuring an et'fi('-ient eutt'ing and stirringol' the soilclose to the plant on. each side, and yet avoiding: injury to it byheaping too much soil upon it or by euttingor bruising" it's hen-Jed orstalk. In this mannerl attain a maximum degree of cultivation andproduetivenoss.

The invention also consists in certain eombinations of. partshereinafter set forth.

In order to make my invention understood, I have shown in theaceon'ipanying' drawings a means for carrying it into effect.

In said drawings, Figure 'l is a rear view of a disk cultivatorembodying my invention. Fig. 2 is a horizontal section on line 2 i, Fig.

' l i. Fig. 3 is a plan view of the gang-shaft detached. Fig. L is asectional view of one of the inner disks and its simporting-sleeve. Fig.5 is a rear view of the gang standard and arch. Fig. ti is a horizontalso tion of the same on line (i (5, Fig. l ig. 7 is a sectional view online 7 7, Fig. 3.

Referring to the d rawings, A represents the eonverging beams of thetongue, connected at their rear ends by the brace-rod (l. and se 0.Lired to the axlotreeA. lhevlatter is mounted in any suitable mannerupon the wheels WY, so as to be at a considerable height above theground, shown in Fig. l. 1] L are the drag-beams, of any preferredconstruction, preferably converging at their forward ends, as shown, andthere connected with the tongue or draft-frame in a wellknown manner. Attheir rear ends the dragbeams are spaced and held apart by the usualarch, it, the lunizontal. arms [of which are secured to said liieams byclamps Z" By these clamps the beams L and the ca. gs carried therel'iymay be adjusted t'arther apart or nearer together, as may be desired,the clamps beingfor this purpose moved inward or outward along arms [andtightened up at the proper points. Plates secured to the upper sides ofthe beams, protect them and serve as a hearing-surtaee to: arms 1.

b S indicate the gang-standards secu red to beams Ti, preferably boltedto the under side thereof by bolts s, as shown, and included, also, byclamps I, it dcsiresi. The gangstandards are provided with arches 'l,Figs. 5 and ti, wh ieh maybe :ulvantncemisl y formed by being cast inone piece with the standards. To the curves ot' said arches areconformed the curves of the transverse portions 1 of the gang-yokes Yand clamps y are provided, consisting, for example, otI staples 1adapted to be passed through or around the arches 'l, and having nuts gon their screwthreaded ends, by which elan'ips the arches 3 may besecured in various positions relative .to arches 'l. The gang-yoke Y maythus be adjusted, as will be readily understood by reference to Fig. 5,so that the games may conform to the slopes of the ridge which willordinarily be formed along the row of plants,

and each disk out to the same depth. By

this means of adjustment the cultivator may also be adapted to otherconformations of g'lOlllltl, as may be desired.

Usually the standards S will be secured to beams l1 in such positionthat. the gangs will have the proper average inclination or angle tothelineo't' advance. Such angle may,ho\vever, be obtained by the meansof adjustment shown best in l ig. U, or by other equivalent means, bywhich the gangs maybe swung .in horizontal planes and clai'nped when at?the desired angle. My clamping device consists of the staples f, already're'li'enred to, one or both of which. are made of su t'ficient width topermit a t'i'irward or backward adjustment of the ends of arches n onarches T, as indicated in dot-ted lines in Ihig. (i. I deem. itpreferable to originally set the standards S so that the gangs will.have the average desired inclination and to modify such angle ascircumstances may require. by means of the clamping devices.

The gangs I are carried by the arms 11 of the gang-yokes Y in the usual.manner. The disks E of the outer and main portion of the gang aremounted upon a RlOOX'G, F, are spaced by collars or thimbles f, and areclamped. rigidly between nuts N, which screw upon the outer and innerends of said hollow sleeve or shaft .lt.

I is a stationary shaft. or journal. passing through the sleeve lnn'mnted in the ends of arms 3 and firmly clamped in place at its outerend by a nut, M, which screws upon its reduced. and threaded end andserves to draw its shoulder I: tightly against the inner :face of theouter of arms 11/. It is evident, however, that other means may beemployed for securing shaft I in place. Upon this stationary shaft thesleeve l and disks I) turn freely when the (llltl\'{tt0l' is inoperation. It will, however, be understood that other well-known 'meansfor mounting the gang-disks so that they will freely rotate may beemployed. For theniounting of the inner disk of the gang, a secondjournal, I, is provided. This I prefer to form in one piece with and asa con ti nuation of the shaft I, though at an angle thereto. While morethan one disk. may be employed for this inner portion of the gang, Iprefer to use but one, and have illustrated such latter ctmst-iaietion.

The inner disk is shown at I and is preferably provided with a sleeve, 1thimblej, and elamping-nuts N. ,ly means of said sleeve it is mountedupon the. second journal, I, so as to freely rotate thereon when in use,being held upon the journal by the nut lllor equivalent fasten in Whenjournalsl and I are formed together, as shown, I prefer to separate themby the flange or collar t ig. 33, which surrounds them at their junct'ure and is rigidly secured in place by being shrunk on or by a pin, asshown at F.

It will now be seen that the parts being in the position shown in Fig.2, in which the dotted arrows 0* indicate the direction. of the line ofadvance, the inner disk, It, may travel very closely to the row ofplants, (a'ltting and disintegrating the soil in 'innnediate proximityto them without unduly heaping up the earth upon their stalks orOl'ilH-FI'WISO inflict:- ing injury, while the main portion of the gang,set at a dit't. -*.rent; and greater angle, ill perat n the usualmanner, turningaiul throwing the earth and cutting the weeds to agreater extent than would be safe for the inner disk in its closeproximity to the plant.

It may often be desirable to change the angle and depth of cut; of theinner disk relative to the outer portion of the gang. I have providedfor conveniently effecting this in "the eonstruotion shown by means of alever,

i", secured to the journals I I, preferably to the flange or collar i,Figs. 4. and 7. 3y oscillating this lever the shaft I will be turned.Such oscillation may be caused by the toe of the driver, or a si fl'ablelever may be employed. I have fou. *Q. that the friction of the parts M11 will. be ordinarily sufficient to hold shaft I in the position towhich it may be turned without applying any catch or holder to the lever1"".

It will be understood that in place of staples y an e( 1ui.'\"alent:tj'astening may be used consisting of simple bolts passing throughlongitudinal slots in part U and through t an irrse is in part. T, thusenabling both or the adjustments llOl'OlllbOfOlfO described to beobtained.

Yokes or supports Y may be attached to the thimblesfj", if preferred.
